Parasite.
The movie (for me) is such a reflection of globalisation, capitalism and the hard truths of the lives of the people at the bottom as well as the top. I really enjoyed its portrayal of class in our modern society and how we, as humans in this society, can be 'parasitic' towards each other. The poor want the riches of the top, and the rich use the poor to enable their high living lifestyles. It really changed my perspective.
